2 Claims. (Cl. 212-83) This invention relates to apparatus adapted to beset up in an open field for the purpose either of stacking hay orremoving hay from a stack.

Heretofore difiiculty has been experienced in ordinary carriers of thistype because it has been practically impossible to bring the wagon intoproper relation to the carrier and, as a result, the load being conveyedhas not been able frequently to clear the stack.

An object of the present invention is to provide a simple and efficientapparatus which can be set up readily in a field and can be adjusted todifferent heights, said apparatus including an extension for the carrierunder which the body of the vehicle to be loaded or unloaded can bepositioned so that the hay can readily be lifted therefrom and loweredthereto and can be transported at a high level so that hay thus canreadily be lifted from or deposited upon the center of the stack.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention consists of certain novel details ofconstruction and combinations of parts hereinafter more fully describedand pointed out in the claims, it being understood that changes may bemade in the construction and arrangement of parts without departing fromthe spirit of the invention as claimed.

In the accompanying drawings the preferred form of the invention hasbeen shown.

In said drawings Figure 1 is a side elevation of the apparatus inposition adjacent to a stack, portions being broken away.

Figure 2 is an end elevation.

Figure 3 is an enlarged vertical transverse sec-- tion through theskeleton beam and the track thereunder, the carrier being shownsuspended from the track, said section being taken on the line 33,Figure 1.

Figure 4 is an enlarged central vertical transverse section through thecarrier.

Figure 5 is a vertical longitudinal section therethrough.

Referring to the figures by characters of reference A designates askeleton beam of any desired length formed preferably of three anglestrips indicated at l, 2 and 3 which are joined by triangular straps lregularly spaced so that the resultant beam is substantially triangularin cross section with a fiat top and with downwardly converging sides,as shown particularly in Figure 3. The ends of the beam can be closed bymeans of triangular plates 5 which also serve to stifien the beam andconstitute a means for attachment to hangers 6. These hangers have headsI at their upper ends from which are extended stems 8, the stems at thetwo ends of the beam projecting in opposite directions but being inalinement.

The beam is reenforced longitudinally by a truss 9 in the form of a rodsecured at its ends to the top of thebeam at the center of the endsthereof andsecured at its center to the center of the bottom of thebeam.

Depending from the bottom strip 3 and the triangular connecting strap 4are rods H] the lower ends of which are secured to cross strips I Iwhich, as shown particularly in Figure 3, have angle strips 12 securedon the end portions thereof. These strips are oppositely disposed withupwardly extending flanges cooperating to form a track. This trackextends throughout the length of the beam A and one end of the track isalso extended well beyond the adjacent plate 5 to which it is connectedby a bracing rod I3.

Depending from the track at a point adjacent to the center of beam A isa strip M.

The beam A is adjustably supported by telescopic standards B formed ofan upper angle strip l5 and a lower angle strip It, the two beingslidably connected so as to telescope one upon the other and being heldagainst relative displacement by guide bands H which embrace the strips,the lower band being secured to the upper strip I5 while the upper bandI! is secured to the lower strip it, these bands being slidable alongthe opposed strips. The construction is so obvious that detailedillustration thereof is not deemed necessary.

A pulley I 8 is carried by the upper end portion of each of the lowerstrips l6 and a drum or windlassl9 is carried by the lower portion ofsaid strip l6. To this drum is secured one end of a cable 20, said cablebeing extended upwardly over pulley l8 and thence downwardly, its otherend being attached to the lower portion of strip l5 as indicated at 2 lA carrier has been indicated at C. This can be of the same generalconstruction as the carrier shown in Patent No. 1,421,102, issued to meon June 27, 1922. The carrier is provided with wheels 22 adapted totravel along the track I 2. Sheaves 23 are carried by the lower portionof the carrier. Arope 24 is fastened at 25 to the carrier and has a freeend portion 26 extending in one direction from the carrier. The otherend portion of the rope extends in the opposite direction thereof andlongitudinally under the track 12, it being movably supported at one endof the track by a pulley 2?. The rope 24 is provided with a bight 28depending from the carrier C and this bight supports a sheave 29 havinga hook 3B and an upwardly extending eye 3|. This eye, when raised, isadapted to engage a latch 32 and means are provided in the carrierwhereby the latch can be released when it comes into contact with thetrip [4. This means can be in the form of a slide 33 adapted to dropinto the path of a portion of the latch when said latch is elevated intoholding position. The construction of the carrier and the partsassociated therewith is substantially the same as disclosed in my patenthcreinbefore mentioned and, therefore, constitute no part of the presentinvention.

When it is desired to set up this apparatus for the purpose of stackinghay, the standards B which are provided at their upper ends with :3

sleeves 34 journalled on the stems 8, are set up so as to convergeupwardly, thereby supporting the skeleton beam A above the point wherethe stack is to be located. By means of the windlasses l9 and the cables20 these standards can be elongated so as to raise the beam A as far asdesired. Suitable means, such as pawl and ratchet mechanism 35 will ofcourse be provided for each Windlass so as to prevent retrogrademovement of the Windlass after the standard has been elongated. Thisratchet mechanism is of the conventional form aand detailed illustrationthereof is not deemed necessary.

Before the parts are set up as explained the carrier is of course placedon the track l2 and the rope adjusted. This carrier is free to movelongitudinally of the track and when it is on the extension of the trackas shown in Figure 1, it can support the hook 30 and any hay fork or thelike which may be suspended therefrom, directly over the load to becarried. By paying out rope 25. the sheave 29 can be lowered forengagement of its hook with the load and thereafter, by pulling on oneend of the rope 2 1, the load can be elevated and the carrier drawnalong the track [2 to a point exactly over the center of the positionwhere the stack is to be formed. At this point the trip l4 will releasethe sheave 29 for gravitation with its load, in

an obvious manner. Thereafter by pulling on the other end of rope 24,the carrier can be moved in the opposite direction on track I2 andbetween one pair of standards B so as to assume a position on theextending end portion of track l2 directly over the load to be carried.The operation can then be repeated. Obviously the foregoing operationwould be reversed should it be desired to remove hay from a stack andtransfer it to a vehicle.

Importance is attached to the fact that the track is suspended from askeleton beam. This provides strength and lightness and enables a trackof considerable length to be utilized in connection with the apparatus.

What is claimed is:

1. Apparatus of the class described including a skeleton beam comprisingconnected spaced strips, end plates secured to said strips, hangersextending therefrom, stems projecting from the hangers, a pair ofstandards pivotally connected to each of the stems, all of the standardsconstituting means for supporting the skeleton beam, each of saidstandards comprising telescopically connected members and means forshifting the members relative to each other, a track suspended from thebeam and having one end portion extending between the standards'of onepair and beyond the end of the beam, a brace connecting the outer end ofthe extension portion of the track to one of the stems, and a carriermovable along the track and onto and off of the extension.

2. In apparatus of the class described the combination with adjustablesupporting elements, of a structure mounted therebetween and includingangle strips disposed in parallel relation, connections therebetween,said strips and connections providing a skeleton beam angular in crosssectional contour, a truss rod secured at its ends to the end of saidbeam and at its center to the bottom thereof, a track parallel with andbelow the beam and having one end extending therebeyond, spacedconnections between the track and the bottom of the beam, and asupporting connection between the projecting end of the track and oneend of the beam.
